You can create Get Up! 2,3,4,5...250 etc. (like FIFA17, 18 etc.) and change only title screen or whatever (or even nothing) and release it (entering this contest is not necessity for releasing your stuff or is it?). Only that then you can't participate in this ABBUC contest with its rules. That's all. There are tens of new games for 8bit Atari every year and only small fraction participate in this contest.
Yes of course. Not releasing at the Asc is a decision everybody can make anytime.
Only Asc gets smaller by time. But how to support the programmers/artists and in this way the Atari? Or support the best game of the year? (like in the KAZ competition)
